MSD Street Fire CD Ignition

MSD Street Fire CD ignitions are perfect for budget-minded enthusiasts. Street Fire CD ignitions offer capacitive discharge technology that fires a series of multiple sparks for 20 degrees of crankshaft rotation when the engine is running under 3,000 rpm. This ensures complete combustion and produces great throttle response with a smooth idle. MSD’s Street Fire CD ignitions are built within a durable cast aluminum housing and easily connects to points, amplifiers, and magnetic pickup distributors. There’s even an adjustable rev limiter (100 rpm increments) for overrev protection!
